Effects of the five compounds on Nrf2, GR, GPX, and NQO1 mRNA expression in A549 cells. (a) A549 cells were incubated with 5 or 10 μM GLL, ILF, LCA, and LIA and 50 or 100 μM 18β-GA. Those expression levels were monitored by semiquantitative RT-PCR assay. (b) The expression levels were monitored by quantitative real-time RT-PCR. Data points and error bars represent the of at least three experiments () for each concentration tested; ().
